Watch the video (myefi.blog/2019/02/20/applications-that-wow-dual-day-night/) to see a dual/day night image printed on backlit fabric and installed in a Vivalyte lightbox.

To create this effect, two separate files are required for the dual day/night backlit graphic. The final image is a three-layer print: colour image, white flood, colour image.

The front image is visible when the lightbox is turned off. The white flood conceals the back image. When the lightbox is turned on, the back image is illuminated, creating an effect that is now visible.

For our display, Vivalyte created a custom script to sequentially illuminate the grid of programmable, white LED lights in the lightbox. When the lightbox is turned on, colors from the back image of the print are revealed, creating the realistic northern lights effect shown in the video.
